I think I would want to put a non-riding day between your tempo/LSD and your LSD/Interval rides. So it would be:

Tempo
Off bike or weights
LSD
off bike or weights
Interval
Recovery
Off bike or weights

Your weights days after temp & LSD should be fairly easy days - just enough to maintain. Your weights day after recovery could be heavier upper body, and lighter lower body, since the next day you have a tempo ride.

Do not increase your mileage more than 10% in any week. So, if you're doing 50 miles/week this week, next week you'll do 55 miles, then 60 miles, 66 miles, 73 miles, etc.
